> Except for those in power, of course.
The horrifying thing is that those people are the real targets. Most people do what they're told and eat their slop. The juiciest fruits of spying come from being able to keep someone out of power, being able to put someone in power, and being able to control people who are in power.
Even when they're targeting consumers, they're targeting the consumers who control the purse, and the wealthiest are the most valuable. Mass surveillance attacks power that poses a threat established power.
Tapping everyone's phone is something that even with AI costs far more than it is worth. That's why you look for other, rougher indicators in order to make lists of people who get expensive surveillance. While "expresses opinions online" might get you on the list, "being a congressperson" is also definitely one of those indicators, or "being an executive at a medium-large business."
We're pretending like the real problem is that they're going to be able to find out that I really like hot dogs and then collude to charge me more for hot dogs online (which definitely is a problem) but the real problem is that you can tap the car of a senator, figure out they're cheating on their husband, and use that to get permission to murder a bunch of people in Ecuador (or Arkansas.) It's a complete loss of power except for the people at the top of the chain.
You can use someone's driving habits and/or phone info in order to set them up to be framed for a murder, or any sort of crime. Accusing people of sexual assault has always been a tool because there's no hard evidence that can be asked for by law enforcement, it's just mind-reading and deciding who you like; and you can trash somebody in the media without ever charging them. Now you have the full gamut of crimes with very convincing circumstantial evidence, and actual data forensic evidence, which can easily be planted.
The West has been run by graft networks, and since WWII it's been gradually flipping to be run by extortion networks. Graft networks are at least bottom-up - you pay for better; extortion networks are top down - you pay to avoid worse. It's a movement from a caricature of democracy to a caricature of dictatorship.
The person who is at the top will not have any cameras pointed at them. There will be no way for you to determine who they are. Their lieutenants will be the most blackmailed people on the planet. Having things that can be used against you, and having the ability to convincingly lie about why you're doing things will be the most valued quality that one can have in your career. We're mostly there already.
